Matter beats out antimatter in experimental echo of creation

Imbalance at Illinois particle accelerator could presage major physics breakthroughs

4:16pm, May 19, 2010

Less than a trillionth of a second after the Big Bang, another tumultuous event happened. Although the cosmos was born equal parts matter and antimatter, which destroy each other upon contact, matter somehow began to dominate.

Physicists now have uncovered a new clue about what caused the fortuitous imbalance, which led to the existence of galaxies, planets and people.

The new result is based on eight years of studying the decay of trillions of short-lived particles, called B mesons, that are produced during high-energy collisions at the Fermi National Accelerator Laboratory’s Tevatron particle collider in Batavia, Ill. Scientists on the T
